It is probably difficult to generalize, but, I am pairing my Nord to My Technics KN7000 to use the organ left hand part on my Technics. This TX only from KN's midi out. It works fine but I keep getting stuck notes and have to hit the Nord panic button. I set up the same thing on my G70 and no problem. These are two TOTL arrangers with sophisticated midi implementation. I have gone through all parameters for a cause. The big question is whether to abandon the KN7000 in this configuration in favor of the G70. I don't give up easily, but I can't always be afraid of a stuck note during performance. This is the simplest midi application there is, and there should be a simple answer besides I am not getting a note off message.
